JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Review Array Methods, Iterating and Two-Dimensional Arrays

Combining arrays into a single string.

I don't remember the function name that allows me to answer the below question correctly. What is it? Also, please tell me where I can find a list of javascript functions I can refer to in the future. I already looked through MDN but I couldn't find it.

Finish the code by adding the array method that combines all of the items in an array into a single string.

var students = ["Sally", "Joan", "Raphael", "Sam"]; var message = "Hello " + students.?(", ");

The join() method joins all elements of an array (or an array-like object) into a string and returns this string.

You will find a list of array methods on the left side of the MDN Array page. They are all links, so click on any method name to go to the page for that method. Also you can just hover the cursor over a method to get a description tooltip.
